Lack of audio fx keyframes?

I've not really been into audio fx, but recently wanted to have a bit of reverb on a piece of music, slowly changing back to the original part way through. The slider is there in reverb to increase or reduce the effect, but it would have been nice to have keyframes there to control effect over time.
I've got SF but cannot see keyframes there either.

Am I missing something along the way?

BTW using V4 for its reliability

I can Preview the Video in SF. I can set markers in SF. I'm using SF7b Build 301

My workflow:

If using V4,V5 or V6 using AVI files:

1/- Locate in Explorer

2/- Right Click > Open in Sound Forge

3/- Use the Video Strip PLUS Preview and/or ExtMon Preview to postion SF markers

OR:

1/- From Trimmer

2/- Right click on Audio section > Open in SF


Now you can "open" copy of the audio in SF from the Vegas timeline, no video comes with it. I thought I had this happen once this morning, but it apears not.


Done!

Now with Media Manager in V6 you have to go VIA the Trimmer - it is not a direct action.

Hope this helps ..

I don't know what's about V4 but since V5 you can have keyframed audio fx by using the automation control onto track fx.

Marco, how do you increase or decrease "REVERB" over time? I understand the Track Automation and the use of POINTS and such. But how do you addd and connect - say REVERB - to the video as per our friend, mel58i, wishes? I'm listening.

One simple way, duplicate the track. Set reverb to wet out only and use a volume envelope to control the amount of reverb coming from the second track.
Other way, use an automatable FX, the insert automation envelope, that'll open a list of things from that FX that you want envelopes for. Play away to your hearts content.

Insert an FX bus, add a reverb, set the reverb to 100% wet. Set the track to pre fade.
Now, use an FX envelope on the track to fade in/out the reverb. If you want to fade the reverb up and the original audio down, then fade the audio down using an envelope and fade the reverb up using same. If it's prefade, then you'll end up only hearing 'verb and no original audio.

Many thanks to you all for replying. It seems that there are many ways to "skin a cat".
The way I had envisaged was to split the audio into two. Apply the reverb to the first part of the split, then extend the unaffected part at the beginning by the same time as the mix, then crossfade the two so as to maintain sync.
Bob's idea of duplicating the track, then have a vol env to fade one up and the other down seems fine too.
Spot's scheme is very versatile using a bus (spot on!) I've played with them before, but if you don't use then regularly you soon forget!
Pity there is no actual way using keyframes, it would be very easy if there was, the video ones are a dream to use.

Thanks again to a great set of experts.

Spot, I was trying to get to the, " . . . but it would have been nice to have keyframes there to control effect over time." .

Try adding POINTS at the intersection of Video MARKERS on the FX bus "line" - yeah?

Technically, you DO have keyframes. They are called "envelope points." They live on the track, just like a track-based effect for video. The difference is, that you don't have a keyframing timeline window in the FX. Keeping in mind the effort to duplicate the analog world, there is no "keyframe" for these actions in the analog world where in the video world, there often has been some form of time-based correction capability. I realize it's not the same, and it definitely departs from Vegas tendency to manipulate audio in the same manners as it manipulates video. But having true keyframes for audio would tick the audio guys off even more, IMO, and some of them think Vegas is too video-centric as it is. Buses/Auxes are the way you'd do this in the analog world, and therefore you would want your NLE/DAW to function in much the same way, IMO.

True . . true . . true . .

Frankly, I'd like to use a physical "knob" or fader/slider to do this job . . keep that which is truly analog within the analog field. Hearing audio on my speakers and moving a physical "thing" would be my pref!

I was attempting to get a k/f or POINT solution for our friend here . . .

Grazie

If you want a physical knob, then just program one. Use something like the Mackie, use the Griffin, use a Behringer, use a Tascam, or even an M-Audio Oxygen keyboard, and you've got physical knobs, but they're still just adjusting envelope points. (keyframes)
